The second fasciculus of the Proceedings, Series II.,which should have 
been paged from 33 to 64, was, by an unfortunate oversight, renumbered 
1 to 32. In the present contents and index, to avoid confusion, these mis- 
numbered pages are considered and placed as if they were paged cor- 
rectly; e. g., a title referred to page 45, in the index, is found on the 
second page 13 (45—32) of the Proceedings.
